I am a behavioral biologist working on the evolution of cognitive abilities in primates. Using experimental set-ups, I investigate variation in cognitive abilities on the species, as well as individual level in wild non-human primate species. Combining ecological measures as well as observations of social behaviors with experimental methods, I aim to identify fundamental factors explaining the parallel evolution of ecological and social intelligence.
Recently, I studied intra- and interspecific variation across various cognitive abilities in sympatric lemur species. My current work in the Technological Primates group focuses on the evolution of tool-using behavior by investigating intra- and interspecific variation in tool-using behaviors in bearded capuchin monkeys in Brazil, long-tailed macaques in Thailand and Western chimpanzees in Ivory Coast. Including ecological measures, natural observations, as well as field experiments, my comparative research aims to give insight into the covariation of cognitive abilities with ecological as well as social factors.
